summary: Returning to the life he built after his father died (Slight AU; the curse was broken years ago and Mikael was killed in Chicago, so he only met the Salvatores and Elena)

Mystic Falls, 1974

"This is my daughter Elizabeth." She told him looking over at the two year old girl playing with the corner with her toys. The couple had been together for over a year and it was Klaus's first time meeting her daughter. The two met in 1972 when Elizabeth was first born, becoming a couple when she was almost a year old.

"Liz, can you come here sweetheart?" Y/n called out to her daughter. Elizabeth looked up from her toys noticing the man next to her mother. She instantly got up, running up to the two, Elizabeth had always been a people person, waving to anyone she saw at the grocery store or in the park.

"I'm Elizabeth, but mommy calls me Liz." She gave me a toothy grin. Klaus looked over at his girlfriend silently asking for permission, Y/n nodding. He got down on his knees to match her height.

"Hello, love." He spoke in his British accent which made Liz giggle. "I'm Niklaus, but you can call me Klaus or Nik."

"Do you wanna play dolls with me?" She asked him playing with the end of pigtails.

"Of course." He smiled. Liz grabbed his hand dragging him back to her corner. Klaus looked back at Y/n who was laughing giving him a wink before going back into the kitchen.

1977

"Are you ready for school?" Klaus helped Liz put on the straps of her backpack, the two standing outside of the elementary school. Liz smoothed down her dress for the fourth time since they got outside.

"Are they going to like me?" She looked at him.

"Who wouldn't, you are smart, kind, everyone is going to love you and you're going to have so many friends." Klaus ran his hands over her hair, keeping down her baby hairs. "I love you Lizzy, you have a good day."

"I love you too daddy!" She hugged before running into the building. Klaus stood wide eyed not moving, not noticing Y/n walking up behind him.

"Are you alright?" She ran a soft hand down his arm.

"She called me daddy." He spoke softly. "First time she ever said that."

"Oh!" Y/n gasped. "Well I-uh..."

"It's alright love." He turned around cupping her face. She placed her hands around his wrist, the two continuing to look at each other. Y/n never loved someone as much as she loved Klaus, it was a miracle that he came into the both of their lives, he was someone she wanted to spent the rest of her life with.

"Marry me." Y/n whispered, she didn't even know if it was loud enough for him to hear her.

"You beat me to it." He chuckled, removing his hands from her place, digging into his pocket, pulling out a small velvet box. He opened it up seeing the princess cut diamond ring sitting inside.

"Oh!" She covered her hand with her mouth, tears welling her eyes. "Yes, yes, a thousand times yes."

"I didn't get to ask you." Klaus smiled, taking out the ring, removing her left hand from her mouth, sliding on the engagement ring on her finger, kissing her knuckles.

"Y/n Mikaelson and Elizabeth Mikaelson." She spoke the name of her and her daughter. "I love it."

"And I love you." He smiled, kissing her.

The next few months were spent preparing the wedding between Y/n and Klaus and finding out the secret Klaus bore.

"Are you sure you want to do this?" Klaus asked for over the thousand time. After Y/n found out Klaus was a vampire, she wanted him to turn her.

"Yes, my love." She said. "I've told you yes every single time."

"I just don't want you to regret this." Klaus confessed. "This isn't no going back."

"You and me together." Y/n confessed. Klaus kissed her before biting down in her wrist, the blood seeping out. He brought it up to her lips, Y/n slowly ingesting trying not to gag from the taste.

"Will it hurt?"

"Only for a second, then it's all over." He confessed, slowly bringing his hands up to her face.

"I love you." She confessed.

"I love you too." Was the thing she heard before her sight turning black.

1990

"Elizabeth Mikaelson!" The two cheered watching their daughter walk across the stage grabbing her diploma. Liz made eye contact with her parents, blowing them a kiss before stepping off the stage.

The three made their way back to the Mikaelson household for a private celebration between the two.

"I'll get it!" Klaus made his way out of the kitchen when they heard the doorbell ring. Liz and Y/n continued to enjoy their cake when Klaus came back in with a solemn look.

"Is everything alright?" Y/n looked up at her husband.

"He found me." Klaus referred to his father. "I-I have to leave before you two get hurt."

"It's alright my love." Y/n confessed. "Go, keep yourself safe, we will meet again."

"I'm sorry sweetheart." Klaus hugged Liz kissing the top of her head. When Liz turned 14, she started to take more notice how both her mother and father never aged, the two told her about their lives and the how danger Klaus's father was. "I wish this wouldn't happen."

"It's alright." Liz sniffed. "You'll come back."

"I'll be back." He confessed.

Season 3

All the Originals had been awoken again. Klaus had been working for decades trying to destroy his father so he could return to his wife and daughter once again without needing to look over his shoulder. The Mikaelson's stood over their dead father's body, finally believing to breath for the first time in thousand years, they weren't being hunted.

"Not now!" Klaus pushed pass Damon, Stefan Elena as they stood outside of the Mikaelson household.

"Hey don't walk away from me!" Damon yelled looking over at him as he sped towards town, the three following him.

"What is he doing?" Damon said to himself watching Klaus walk into the sheriff's station.

"Look at you." Klaus smiled. "Running the station, I knew you were a natural born leader."

"Dad." Liz turned around to face him, still as young when she was 18. "You're back?"

"Of course, I'm okay, it's all over now." He confessed. He slowly made his way towards her wrapping his arms around her. Liz stiffened slightly before relaxing letting her emotions take over her, crying into his shoulder.

"Your mother?" He asked.

"It was bad for the first two years it was bad, but after I had Caroline, it got somewhat better." Liz confessed.

"Caroline?" Klaus raised an eyebrow.

"She's my daughter, your granddaughter." Liz smiled.

"A granddaughter, could I meet her?" Klaus questioned.

"She's at the Mystic Grill, with Y/n. They have weekly lunch." Liz said. "I'm happy you're back."

"Me too." He kissed her head before leaving the sheriff office.

Y/n Mikaelson and Caroline Forbes sat at a table in the Grill having their weekly lunch. The two posed as sisters, instead of grandmother and granddaughter so the locals wouldn't ask questions, and if someone ever asked if Y/n looked familiar, she would say 'I was named after my grandmother and have many similar features'.

"You two need to leave." Damon came into the Grill up to the two girls, Elena and Stefan following.

"What's going on?" Caroline asked.

"There is someone very dangerous in town and was speaking with your mother and maybe on the way here." Damon confessed.

"Who is it?" Y/n asked setting down her fork.

"It's-" Damon started.

"Klaus."

"Yeah how'd you know?" Damon looked over at Y/n his eyebrows furrowing.

Y/n stood up, pushing past Damon running towards the door.

"Oh, my love." Y/n flung herself around Klaus, burying her head into the crook of his shoulder. "You're alright?"

"Everything is alright, I'm back." He smiled.

"Forever?" She looked up at him teary eyed.

"Forever." He kissed her forehead.

She smiled, grabbing his hand, bringing her back to her table where Caroline still was.

"Caroline, sweetheart, this is the man I told you about." Y/n smiled.

"You're Klaus." Caroline looked up at him with a bright smile. Her grandmother always told her about her true love growing up. He nodded, Caroline getting out of her seat, hugging him.

"Are you two crazy!" Stefan exclaimed.

"I have a secret to confess." Y/n looked at the three of them. "I'm not Caroline's older sister, I'm her grandmother. Liz's mother. Now please leave so I can be with my husband again, thank you goodbye."

"Feisty." Klaus chuckled wrapping an arm around her shoulder, resting his head on hers. "Come, let's go get our daughter and we can meet my family."

"Your siblings?" Y/n asked, Klaus told her some stories of them when they were married but she never got to meet them before he left.

"Yes." He smiled continuing to look at her.

"You're staring." Y/n laughed quietly.

"Let me, I haven't seen you for decades." Klaus squeezed her hand thrice.

"Aww this is so cute!" Caroline squealed snapping a photo of the two.

"She's just like Elizabeth." Klaus observed.

"You have no idea." Swinging their hands back and forth. "Come along Caroline, let's go find your mother."
